Fixing Windows 7 Beta 64bit Blue Screen of Death (BSoD) tdx.sys

I have been using Windows 7 Beta (Build 7000) on my laptop since it became available. I have been very pleased with this new version and looking forward for its RTM. Today, I decided to install Windows Beta 64bit on my desktop machine as well. Everything was fine, until I started getting the following Blue Screen of Death (BSoD):




After some research, I found that the problem is related to my antivirus (AVG Fee) and a network shared drive (DNS323 - Linux based using Samba).

After multiples BSoD, Windows 7 finally suggested a solution to my problem:




The problem occurs because of an incorrect behavior in a system component that occurs when Server Message Block (SMB) connections go over Transport Driver Interface (TDI). My network shared drive uses Samba, which is a reimplementation of SMB. The hotfix can be found at:
